Abstract
The receiver signals are split in two quadrature carriers. Elimination of distortions connected with signal components on both carriers is done on the basis of a decision taken by a decision circuit which directly recognises the signal phase characteristic angle and delivers sine and cosine functions of this angle as signals which separately carry out for both quadrature components the elimination of distortions connected with signal components on both carriers. The levels of the phase and quadrature components are passed to a multiplexer.
